WINDOW-HINGE.

Patented April 23,1907.

To all whom it may concern.-

Be it known that I, ROBERT S. DANA, of Hampton Falls, in the county ofRockingham and State of New Hampshire, have invented certain new anduseful Improvements in Window-Hinges, of which the following is aspecification.

This invention relates to attachments connectible with the sashes andframes of windows for enabling the sash to be swung inward to permit theoutside surface of the pane to be washed. The cleaning of windows inhigh buildings is attended with difii culty and danger, because theworkman must stand on the sill in order to get at the outside of thewindow. Frequently there is no provision whatever to secure the workmanagainst falling.

My invention has for its objects to provide a hinge which will enablethe sash to be swung about one of its rails into the interior of a roomso that its outside may be made accessible from the floor; to provide asteady ing device adapted to guide the lower part of the sash andsupport a portion of the weight thereof when it has been turnedinto thisposition; to provide a catch which will hold a detached sash suspenderand support the counter-balance weight when the sash is turned inward;and to provide a connecting device whereby the upper or outer sash maybe engaged with the lowersash and swung simultaneously therewith.

In carrying out these objects, I provide the devices hereinafterdescribed and-illustrated in the accompanynig drawings, in which,- 1

Figure 1 represents a fragmentary elevation of one side of a window.Fig. 2 represents a vertical cross section of the same, as seen from theright of Fig. 1. Figs. 3 and 4 represent perspective views of the upperand lower portions of a window sash and the ad jacent parts of theframe,showing the devices which permit swinging of the sash and which supportthe same when thus swung. Fig. 5 represents a horizontal section of thewindow. Fig. 6 represents a similar view, showing both sashes swunginward. Fig. 7 represents a vertical section of the window, showing inelevation a catch for supporting the sash counter-balances when thesuspending cords are detached from the sashes. Fig. 8 represents anelevation of the catch in connection with a supporting cord andguidepulley. Fig. 9 represents a perspective view of the catch. Fig. 10represents a perspective view of the upper swinging, corners of thewindow sashes. Figs. 11 and 12 represent vertical and horizontalsections of a device for holding the detachable stopzgbead of the windowframe in place. Figs. 13 and 14 represent perspective detail views ofthe same device. Fig. 15 represents a fragmentary sectional View,showing a device for holding the two sashes together. Figs. 16 and 17represent respectively an elevation and a vertical section of thedetachable hinge for the sash. Figs. 18 and 19 represent horizontalsections, showing the same connected with the sash and frame,representing the sash in two difl erent positions. Fig. 20 represents adetail perspective view of the swinging member of the hinge. Fig. 21represents a horizontal section of the hinge. Figs. 22 and 23 representan elevation and a cross-section of the socket member or plate withwhich the hinge detachably engages. Figs. 24,25 and 26 represent twoelevations and a cross sec tion of one of the members which partiallysupports and steadies the lower part of the sash. Figs. 27 and 28represent an elevation and a cross-section of the cooperating steadyingmember. Figs. 29 and 30 represent cross-section views of the window sashin two positions, showing the operation of these members.

The same reference characters indicate the same parts in all thefigures.

Referring to the drawings, I designate by 1 the lower sash of a window,by 2 the upper sash, by 8 one of the side rails of the window frame, andby 4 the stop bead of the frame which retains and guides the lower sash.In

order to permit the sashes to be swung out wardly, I form a portion 41of the stop bead on the side of the frame opposite to that shown in Fig.1, so that it may be removable,

and normally secured in place by means of a button 5 which has two lugs51 capable of projecting through a slotted plate 6 into a socket in thestile 7 of the frame. The button 5 has a squared hole. 52 into whichprojects the end of a key 8 extending through the section 41. The plate6 is secured to the stile of the frame and retains the bead when the keyis turned so that the lugs 51 extend transversely, as shown in Figs. 11and 12.

On the stop bead 4 is attached a plate 9 which supports a pivotedswinging member 10 that is adapted to engage a detachable socket member11 fastened to the lower sash. The plate 9 has a central recess 12 largeenough to receive the swinging member 10 so that the latter may restflat against the bead 4. The portions of the plate 9 on each side of therecess form wings in which on the adjacent edges are pressedprotuberances 13 which form open-sided sockets on the side of the platenext the bead. As the plate is of ductile sheet metal, these sockets areformed by a simple pressing or stamping operation. Within the socketsare held the pintles 14 projecting laterally at one end of the swingingmember 10. The other end of this member is bent outward, and then backupon itself, forming a head 15, between which and the main portion is anarrow opening. In the opposite edges of the member 10 just at the bendare recesses 16. When the mem ber 10 is turned back into the recess 12,only its head 15 projects, but when it is swung outward toward the sash,it lies in the path of movement of the socket member 11. This memberconsists of a metal plate having in the center of its lower edge a slot17 of which the edges are divergent at the bottom. The plate has itsside and top edges bent back, and is formed with lugs 18 by which it maybe secured to the sash. The object of bending back the edges of theplate is to offset the middle portion thereof from the sash so as toleave a space to accommodate the head 15 of -the swinging member 10.

When the window is closed, the socket plate 11 is below the hinge, butupon raising the sash, the socket member is brought above the hinge,whereupon the swinging piece 10 may be turned toward the sash and thelatter lowered. This will cause the slotted plate to embrace and enclosethe head 15 which will be locked in the slot by means of one of thenotches 16, and support the weight of the sash. Upon removing thedetachable bead section 41, the sash may be swung inward into the room,as shown in Figs. 6, 19 and 30. The swinging member 10 and socket member11 may be said to constitute a carrying device for the sash.

For holding and steadying the sash after it is thus turned and while itis being washed, I provide near the lower portion an interlockingcoupling consisting of the plates 19 and 20, of w 'ch the former issecured to the bead 4, and the latter to the sash. The plate 19 has anoutwardly turned lip 21 and a recess 22 in its interior, said recessforming a horizontal shoulder 24 and an upstanding bar or strap 25. Theplate 20 has a tongue 26 partially severed therefrom and bent over.These plates are so located that when the hinge is engaged with the late11, the tongue 26 is exactly at the heig t of the recess 22.

Thereupon when the sash is swung inward, the tongue 26 hooks into plate19 and partially embraces the bar 25, preferably resting upon theshoulder 24 so as to support part of the weight of the sash, and at thesame time retaining the lower portion steady and preventing twisting ofthe hinge. This engagement, however, is not such as to prevent awithdrawal of the tongue 26 from the recess 22 at any time andregardless of the swung position of the sash, said tongue simply passinginto said recess and being free to'be withdrawn by moving the lower endof the sash in a direction parallel with the plane of the tongue, thismovement not affecting the engagement of the carrying device. It is tobe understood, however, that no actual engagement of the plates 19 and20 takes place until the sash has been swung from its normal position..During this swinging movement the tongue 26 enters the opening in theplate 19. Prior to such movement the members or plates are inoperativerelatively, permitting the sash to freely move to carry the plate 20 topoints above or below the plate 19.

It will be seen that the hinge and socket plate 11 form a couple nearthe top of the sash, the members of which are adapted to engage when ina predetermined position and support the sash, permitting it to beturned laterally, while the members 19 and 20 constitute another coupleat the lower part of the sash and-dissimilar from the first couple,adapted to interlock after the sash has been turned, the latter couplebeing disengageable regardless ofv the swung position of the sash asabove described. This construction permits of the sash being entirelyremoved from the frame without removing the stop bead which carries themembers, by simply swinging the sash, disengaging the members of thesteadying device and then raising the sash to disengage the members ofthe carrying de vice. The reversal of this operation permits of theinsertion of the sash into the window without the requirement of theremoval of both stop beads or the adjusting of a heavy sash to providean engagement at a plurality of diversified points. Prior devices forpermittingwindow sashes to be turned inward have usually consisted ofidentical hinges at top and bottom which can only be connected togetherwith difficulty and which are not disengageable independently. By mydevice, wherein I have only one hinge, the same can be easily connectedby holding the swinging member with one hand against the sash, andlowering the latter with the other hand. Then the second coupleautomatically engages upon the sash being swung.

I have described the plates 9 and 19 as being mounted upon the stop bead4, while the complemental members 11 and 20 are mounted on the sash, butit is obvious that the relative location of these parts may equally wellbereversed, the plate 9 being secured to the sash, and the member 11 tothe bead with its notch pointing u ward, and the plates 19 and 20 beingsimilar y reversed. To protect the woodwork against injury by theswinging hinge member 10, I interpose between the plate 9 and the partof the window to which it is secured a thin face plate 27 (Figs. 18 and19) of resilient metal which extends over and encloses the rear sides ofthe sockets 13'.

The cord, chain or other suspender which is connected with the sideof'the sash opposite to that at which the hinge is connected, isdetachable and may be removed from the groove 28 in which it iscontained as soon as the sash swings clear of the frame. The suspenderhas an enlarged end which slips into a hole 29 (Fig. '10) at the end ofthe groove in which it'is held by the frame'of the window and from whichit may easily be pulled out. It is necessary then to secure thesuspender and prevent the'counter-balancing weight from dropping. Thisobject is attained by the plate 30 shown in Figs. 7 to 10, and mountedadjustably above the guiding pulley 31 by means of a screw 32 passedthrough a slot 33 in the plate. The plate has a tapered tongue 34'whichis bent outwardly and extends directly over the groove in the pulley 31,being adjusted so asto permit the cord 35 or other suspender to runfreely'when it is in the groove, but to grip itwh'en itis deflectedbetween the tongue and either flange of the pulley, as shown in Fig. 8;The plate may be secured init's adjustedposition y a screw 36 which isheld ina tapped hole 37 and bears 'against'the sash frame, crowding theplate against its guiding screw 32.

The uppersash which is also the outer one,

may be similarly swunginward by lowering it to the level of the innersash, and removing a section 38 ofthe parting bead 39. The lower andinner sash 1 carries near its swinging side and rear surface on thetopof its up per rail, a plate 40 which has an upwardly projecting flangeor lip 42 (see Fig. 15), said flange lying substantially flush with.the-

' outer face of the lower sash, while the upper and outer sash hassecured to the inner surface of its top rail a plate 43 having a hook 144. Normally the parting bead holds the sashes apart sufficientlyso thatthe flange and hook may slide by without touchin when the sashes areraised or lowered, but when the removable section '38 has been takenout, the sashes may be pressed'closely enough together to causeengagmen'tthere- Thus the upper sash is supported by the lower, andcaused to swing with it. Furthermore, the fact that the plate 40 islocated on the top of the lower sash, with the flange extending upwardlytherefrom, while the hook is formed to engage therewith only upon adownward movement of the upper sash, a construction is provided inwhich, when the engagement has been made, causes the lower sash tosupport or partially support the upper sash. Hence, .a disen agement ofthe sash cord and upper sash, afterthe hook and flange have becomeengaged, would not so affect the upper sash as to permit it to drop awayfrom the lower sash. And where the sashes are to be removed, thevertical movement of the lower sash necessary 1n disengag- 1 ing theupper coupling or carrying member, will also be communicated to theupper sash so that under these circumstances both sashes can be movedand manipulated in the same manner. The suspending cords of both sashesnearest the hinge are permanently connected and partially support theweight thereof so that it is not entirely borne by the hinge. The othercord of the upper as well as of the lower sash is held detachably in agroove and socket, and is gripped'when detached by a clampingplatesimilar to that described. i
